Rapid detection of fentanyl, fentanyl analogues, and opioids for on-site or laboratory based drug seizure screening using thermal desorption DART-MS and ion mobility spectrometry
Receiver operating characteristic (ROC) curve framework was employed to investigate the trace detection of fentanyl and fifteen fentanyl-related compounds relative to environmental background interferents.
A tandem ion mobility spectrometer at ambient pressure included a thermal desorption inlet, two drift regions, dual ion shutters, and a wire grid assembly in the second drift region.
